HC-SR501 PIR Motion Sensor
The HC-SR501 PIR Motion Sensor is a low-cost and easy-to-use device that is commonly used in a variety of DIY projects, including simple motion detector. It is a Passive Infrared sensor (PIR) that detects the presence of a human body by sensing the changes in infrared radiation. In the context of a simple motion detector, the HC-SR501 PIR Motion Sensor is used to detect the presence of a human body within a certain range and trigger an event such as turning on an LED.
The HC-SR501 PIR Motion Sensor is highly versatile, it can be used in a wide range of applications such as security systems, automated lighting and more. The sensor is small and lightweight which makes it easy to integrate into a portable device. Additionally, it is also low power consumption which makes it suitable for use in battery-powered devices. The HC-SR501 PIR Motion Sensor is an ideal solution for creating a simple motion detector that is easy to use and reliable.
LED
LEDs, or Light Emitting Diodes, are small semiconductor devices that convert electrical energy into light. They are widely used in a variety of applications, including simple motion detectors. In the context of a simple motion detector, the LED is used to indicate the presence of motion. When the HC-SR501 PIR Motion Sensor detects motion, it sends a signal to the LED and turns it ON. The LED is used as visual indicator of motion detection. These LEDs are small and lightweight which makes them easy to integrate into a portable device. They are also low power consumption which makes them suitable for use in battery-powered devices.
Steps and info:
1. Get correct components as given. You can buy online or offline. I buy electronics components mostly from Amazon.
2. Start connecting the components. If you are new to connecting components in an electronic circuit, then use a Breadboard or you can straight up make connections using Jumper wire. But before soldering components on a PCB or printing a PCB for your circuit, better try using breadboard so that any errors and mistakes can be observed on breadboard and not after soldering. Or do connections in your way.
3. For this project, you don’t need any controller board or upload code. So you can straight up start testing the circuit.
4. Just put your hand or anything infront of the PIR Motion Sensor and LED will light up. If it doesn’t then check connections. Also you can talk with me and the community through discord. All the links to social is given at the right side of this page.
